CCTV shows suspects in former Iraqi MP Ahmed al-Alwani's death

Ex-Iraqi MP Ahmed al-Alwani was found strangled in a Beirut apartment after arriving from Erbil. CCTV footage shows two suspects wearing black suits entering the apartment building on November 5 and later leaving in casual clothes, allegedly to avoid suspicion. Lebanese authorities detained one Lebanese suspect and are searching for two Syrian nationals as Iraqi officials join the investigation.
